Design And Implementation Of Network Bank System Based On J2EE Platform For Commercial Bank

With the development of the Internet, online banks are providing users with more and more information service and financial service. In addition, users are able to easily access the financial business-related online services, including deposits, payment, information inquiry, transfers, withdraw and payment, personal finance, and credit card.Development of online banking systems will solve the problem of limited coverage of bank site, and expand the bank coverage area to everywhere. It is more convenient to provide customers with inquiries, consulting, and information disclosure of market. Online bank extends a variety of financial services from bank counter to the clients, with "zero distance" service. Online banking systems help banks to provide better and more efficient service to clients, and quickly to win a large number of customers, and to break the geographical boundaries to win more high-quality users and capture the market share.The main idea of this thesis is based on the actual needs of the online banking business. Research and analysis on related platform technologies are made. The thesis explores the problems and solutions of the online banking system construction. From the point of software engineering, the thesis makes requirement analysis and design. Besides, security issues of online banking system are studied.Firstly, a detailed analysis of the needs by small and medium-sized commercial bank online banking system is made, and further extracts the system’s functional requirements and non-functional requirements. The thesis also designs network security measures to meet high security demands of the online banking system. After system requirements analysis, four-layer model architecture system based on J2 EE platform is established. Then the thesis carries out detailed design and implementation of the Web tier, business logic, data persistence layer and data storage layer, combined with the solutions. In addition, data warehouse module is designed and implemented to handle data interfaces. After the implementation of the system, testing plan and test cases are made to carry out the system test.
